Description

[Detailed description of the invention] [Industrial use! l'l'] The present invention relates to a display operating device incorporated into, for example, an mj determination device, and more particularly to a display operating device with significantly improved operability.

[Prior Art] In a measuring device such as a spectrum analyzer that examines the frequency characteristics of a signal input manually from the outside, as shown in FIG. In addition to the CRT display 3 for displaying, there are a number of operation keys 4, a power switch 5, a display lamp 6, etc. for operating this chemical constant device and changing the display contents of the CRT display 3. It is arranged.

However, since measurement devices are generally used in combination with a large number of measurement conditions, it is difficult to provide operation keys that correspond to all M1 constant conditions. The measurement device becomes complicated and difficult to operate for those who are not familiar with the measurement device, resulting in a decrease in operability.

In order to eliminate such inconveniences, as shown in FIG. A measuring device has been developed that displays information 8 and has operation keys 9 corresponding to each display area 7 on an operation panel 2 adjacent to a display screen 3a.

In such a measuring device, each operation information 8 is initially displayed in each display area 7 of the display screen 3a, as shown in FIG. 15(a). Then, when the operator operates the operation key 9 corresponding to the display area 7 in which one piece of operation information 8 is displayed, the display content of each display area 7 on the display screen 3a changes as shown in FIG. 15(b). The operation direction is changed to a more specific operation direction 8a.

For example, in FIG. 15(a), when the operation information 8 of the bandwidth [RBW] of a BPF (band pass filter) indicating the frequency resolution in the spectrum analyzer is selected using the operation key 9, as shown in FIG. 15(b), Each display area 7
Bandwidth [Further details about RBWI [Auto] [
Manual] [Bandwidth increase] [Bandwidth 100KH
z-fixed operation direction 8a such as [Decrease bandwidth] is displayed. Then, if the operator wants to increase the bandwidth, for example, he can press the operation key 9 corresponding to the area 7 in which the operation direction 8a for increasing bandwidth is displayed. Then, the operation command for the corresponding operation direction in the corresponding operation information 8 becomes A.
11l is applied to the BPF in the constant device to increase the bandwidth of the corresponding BPF. That is, one 71J11 constant actually changes.

In this way, by sequentially selecting the operation information 8 and operation direction 8a displayed in each display area 7 of the display screen 3a using the operation keys 9, many types of measurement conditions can be set with a small number of operation keys. becomes possible.

[Problems to be Solved by the Invention] However, in such a display operation device, since a plurality of key functions are assigned to the operation keys 9, it is difficult to operate each operation key 9 according to a fixed operation procedure. Otherwise, it is not possible to set the desired measurement conditions. Therefore, there is a problem that the key operation procedure becomes complicated and the operability deteriorates.

In addition, for example, one operation key 9 has multiple functions such as selection of display information (page selection), automatic/manual switching, increase/decrease operation, selection of operation information, and on/off selection of the corresponding operation information. , switching control of the display contents of the display area 7 becomes complicated.

The present invention was made in view of these circumstances, and
The number of key operations can be reduced by arranging two sets of operation keys or three or more sets of operation keys that manually issue operation commands in opposite directions corresponding to each display area that displays each operation information. To provide a display operation device which can be operated without mistakes even by an inexperienced person and whose operability can be greatly improved.

Another object of the present invention is to provide a display operation device that can further improve operability by providing an operation knob in place of the operation keys on the second side.

[Means for Solving the Problems] In order to solve the above problems, the display operation device of the present invention includes a display device formed with n display areas for displaying operation information for a controlled object; n sets of operation keys are arranged corresponding to each display area on the operation panel adjacent to the device, and are used in pairs to manually input a series of related operation commands; When operated, an operation command sending means for controlling the controlled object in response to the operation command from the corresponding Fψ operation key, and operation information displayed in the display area corresponding to the corresponding operation key to be operated next. A display content changing means for changing the content is provided.

In a display operation device according to another invention, instead of the n sets of operation keys described above, n sets of m (m≧3) operation keys for inputting a series of mutually different operation commands are provided. It is set up.

Furthermore, in another invention, instead of the aforementioned n sets of two operation keys, n sets of operation knobs for inputting a series of mutually related operation commands are provided.

[Function] According to the display operation device configured in this way, when it is desired to increase the operation information displayed in an arbitrary display area of the display, for example, the operation information corresponding to the display area can be increased. What is necessary is to operate the operation key on the increasing side of the set of two operation keys provided. That is, if the operation key on the increasing side is operated, the display content of the corresponding display area changes to the display content on the increasing direction. Further, an operation command to increase the corresponding operation information is applied to a controlled object such as an apj constant device.

That is, necessary operation information can be controlled with a small number of key operations.

Further, in another invention, three or more operation keys are arranged, so that, for example, the number of operation keys increases.

In addition to reduction, reset commands, etc. can be executed with a single key operation.

Furthermore, in another invention, an operating knob is provided instead of a set of two operating keys, so that by changing the rotation direction of the operating knob, contradictory operating commands can be input using one operating knob. becomes possible.

[Example〕 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3(a) is a block diagram showing the operating device. This operation display device 21 is constituted by a kind of microcomputer, and the CPU 31 has the functions shown in FIG. 2(b). Then, the measuring device main body 22 as a controlled object is controlled.

In the measuring device main body 22, the signal under test inputted from the signal input terminal 23 is converted by the mixer circuit 24 into an intermediate frequency signal C by the local oscillation frequency signal outputted from the local oscillator 25, and then the BPF (bandpass filter) 26. The intermediate frequency signal C whose passband width (RBW) has been limited by the BPF 26 is detected by the next detector 27 and is converted into a DC spectrum value signal e. After high frequency components are removed by the LPF (low pass filter) 28, , is applied to the signal terminal of the CR7 display 13. A sawtooth wave signal d output from the sawtooth wave signal generation circuit 29 is applied to the sweep terminal of the CR7 display 13 as a sweep signal.

The sawtooth wave signal e outputted from the sawtooth wave signal generation circuit 29 is applied to the sweep terminal of the CR7 display 13 and also to the local oscillator 25. This local oscillator 25 transmits to the mixer circuit 24 a local oscillation frequency signal S having a frequency corresponding to the signal level of the input sawtooth wave signal d. Thus, the spectrum characteristic 12 is displayed on the CR7 display 13, with the horizontal axis representing the frequency and the vertical axis representing the signal level.

An interface 39 and the like for sending a display command to display the coordinate axes and markers 19 to the RT display 13 is connected.

In the RAM 34, as shown in FIG.
Bandwidth parameter memory 34a stores six types of bandwidths in 6 in association with pointers R in 1 to 6; A parameter memory 34b is formed.

Furthermore, in the RAM 34, a bandwidth pointer counter 34C for counting the pointer R, a cutoff frequency pointer counter 34d for counting the pointer V, a page counter 34e for counting the number of pages P of the operation menu, and a page counter 34e for counting the number of pages P of the operation menu are stored. A flag memory 34f that stores an auto flag that indicates that the automatic flag is determined in conjunction with the VBW flag that indicates that the LPB 28 is in an operating state, and an image that stores image data such as the marker 19 and coordinate axes displayed on the CR7 display 13. A memory 34g1 and a display buffer 34h for storing display contents of the display 15 are provided.

The CPU 31 is programmed to execute a process of sending out operation commands to each component of the measuring device main body 22 according to the flowcharts shown in FIGS. 5 and 6. In addition, in Fig. 5 and Fig. 6, Fig. 1 (
The case where the operation menu on the first page shown in a) is displayed will be explained.

The flowchart is started, and in S (step) 1, the flowchart shown in FIG. 1(a) is started.
When the operation key 16 of 2A is operated, the pointer R of the bandwidth pointer counter 34c is incremented by one.

Further, when the operation key 16 of 2B is operated in S2, the pointer R is subtracted by 1. Then, in S3, RA

Search for the specified bandwidth (RBW). Then, the searched bandwidth is displayed as the operation command value 18 below the corresponding display area 14b. Then, in S5, the corresponding bandwidth is set to the BPF 26 via the interface 37. Therefore, the passing bandwidth of the BPF 26 becomes the bandwidth displayed in the corresponding display area 14b.

Further, when the operation key 16 of the IA is operated in S6, the auto flag in the flag memory 34f is set to 1, and the operation command value 18 of [auto] is displayed on the lower side of the display area 14a. Further, when the operation key 16 of the IB is operated in S7, the auto flag in the flag memory 34f is reset to 0, and the operation command value 18 of [MANUAL] is displayed on the lower side of the display area 14a.

Further, when the operation key 16 of 3A is operated in S8, the VBW flag of the flag memory 34f is set to 1,

Five sets of operation keys 16 each consisting of two operation keys are arranged corresponding to the display areas 14a to 14e.
Operation command value 1 for operation information 17 displayed on 14e
8 can be input simply by operating one of the two operation keys 116. In other words, unlike conventional display operating devices, there is no need to perform multiple key operations to input a single operation command value, so key operations are simplified, making it easy to operate even for people who are unfamiliar with this display operating device. Even if there is, I will never press the wrong key. Therefore, operability can be greatly improved.

In addition, since only one of the contradictory functions such as increase/decrease, on/off, auto/manual, etc. is assigned to one operation key 16, incorrect key operations may occur. rate can be further reduced. Therefore, the reliability of the entire device can be improved.

FIG. 7 is a diagram showing a display operation device according to another embodiment of the present invention. In this embodiment, in addition to the five sets of two operation keys 16, for example, three parent keys 41a
, 41b41c are arranged. And these parent keys 41a and 41b.

41, c are each display area 1.4 a to 14 in FIG.
This corresponds to the main operation information 17 of e. For example, the parent key 41a indicates a marker, the parent key 41b indicates RBW (bandwidth), and the parent key 41c indicates VBW (cutoff frequency).

For example, when the parent key 41a is operated, each operation key 16 becomes an operation key for inputting an operation command value for the marker [9]. For example, when the left operation key 16 corresponding to the display area 14a is operated, a marker is displayed, and when the right operation key 16 is pressed, the marker 19 is displayed on the display screen 1.
It is deleted from 3a.

Therefore, in this embodiment as well, since each operation key 16 is assigned only a one-way operation function, the incidence of key operation errors can be reduced.

FIG. 8 is a diagram showing a display operating device according to still another embodiment of the present invention. In this embodiment, a third operation key 42 is interposed between the two operation keys 16. This third operation key 42 is assigned a reset function that immediately returns the operation command value, such as the frequency, set by the left and right operation keys 16 to the initial value or reference value.

Operation knobs 44a, 44 are located at positions corresponding to 4b, .
b, . . . are arranged.

When the operating knobs 44a and 44b are rotated, for example, in the o'clock direction, the operating command value such as frequency increases, and when the operating knobs 44a and 44b are rotated counterclockwise, the operating command value decreases. Even with such a configuration, each t=i production knob 44a
, 44b can each perform substantially the same function as a set of two operation keys 16. Therefore, it is possible to obtain substantially the same effects as in the previous embodiment.

FIG. 11 is a diagram showing a display operation device according to still another embodiment of the present invention. In this embodiment, in addition to a pair of operation keys 16, one operation knob 45 is provided corresponding to the display area 14a. This operation knob 45 performs fine adjustment of the operation command value set by operating each operation key 16. Therefore, he can control his controlled object more precisely.

FIG. 12 is a schematic cross-sectional view showing a main part of a display operating device according to yet another embodiment. In this example,
A set of two microswitches 47 on the internal PC board 46
A, 47b are disposed, and a seesaw-shaped switch 48 that performs the same function as a set of two operation keys 16 is disposed on the operation panel 49 on the front surface. Therefore, pressing the left side of the switch 48 turns on the microswitch 47a, and pressing the right side of the switch 48 turns on the microswitch 47b. Therefore, it is possible to obtain substantially the same effects as in the previous embodiment.

Furthermore, in this embodiment, the microswitch 47
Since keys a and 47b are not inserted at the same time, the probability of key operation errors can be further reduced.

FIG. 13 is a diagram showing a display operation device according to yet another embodiment. In this embodiment, each display area 14a
The display 15 on which ~14e is formed has the spectrum characteristic 1.
It is incorporated into a CRT display 13 that displays 2. In this way, by incorporating each display area 14a to 14e for displaying each operation information 17 and operation command value 18 into the display screen 13a of the CR7 display 13, it is possible to make the screen easier to see.

[Effects of the Invention] As explained above, according to the display operation device of the present invention, it is possible to input operation commands in opposing directions on the operation panel corresponding to each display area where each operation information is displayed. -Group,
Alternatively, three or more sets of operation keys are provided. and,
Each operation key can be input with an operation command value in one direction. Therefore, compared to conventional devices, the number of key operations required when inputting one operation command value manually can be reduced, and even an inexperienced person can operate the device without making mistakes, thereby greatly improving operability. Furthermore, since the probability of occurrence of a manual key operation error is reduced, the operability of the entire device can be greatly improved.

Further, by providing an operation knob in place of the operation keys on the second side, it is possible to finely adjust the operation command value, and the operability can be further improved.
